NASA's TRACERS mission has gathered its first evidence on how space weather acts on Earth's magnetic field. A new paper based on the mission's first year of observations explains how these interactions unfold.
What the first-year observations show
According to a report by Phys.org Space, NASA's TRACERS mission, short for Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites, has collected its initial clues about how space weather influences the magnetic field that surrounds Earth.
The findings come from a new paper published in the Journal of Geophysical Research: Space Physics. Its authors examine early observations gathered during the first year of the mission and set out how these interactions work.
Limits of the early reporting
The available material is limited to the paper's publication and the mission's first-year observations as summarised in one report. Further detail on the physical processes and their measured effects is not part of the verified information for this story.
Open questions
- Which specific magnetic processes do the first-year observations identify?
- How do the findings compare with earlier models of Earth's magnetic field?
